+# Google Vertex AI API Samples
+
+Vertex AI offers everything you need to build and use generative AI—from AI solutions, to Search and Conversation, to 100+ foundation models, to a unified AI platform.
+
+## Description
+
+These samples show how to use the [Google Vertex AI API](https://cloud.google.com/vertex-ai/).
+
+## Build and Run
+1.  **Enable APIs** - [Enable the Vertex AI API](https://console.cloud.google.com/flows/enableapi?apiid=aiplatform.googleapis.com)
+    and create a new project or select an existing project.
+
+1.  **Install and Initialize Cloud SDK**
+    Follow instructions from the available [quickstarts](https://cloud.google.com/sdk/docs/quickstarts)
+
+1.  **Clone the repo** and cd into this directory
+
+    ```text
+    git clone https://github.com/googleapis/google-cloud-ruby.git
+    $ cd google-cloud-ruby/google-cloud-ai_platform
+    ```
+
+1. **Install Dependencies** via [Bundler](https://bundler.io).
+
+    ```text
+    $ bundle install
+    ```
+
+1. **Set Environment Variables**
+
+    ```text
+    $ export GOOGLE_CLOUD_PROJECT="YOUR_PROJECT_ID"
+    ```
+
+1. **Run samples**
+
+    ```text
+    bundle exec rake test
+    ```
